Nine people were arrested in connection with alleged drugs offences as a huge police operation in Dundee continues.

Eyewitnesses said a dozen police vehicles with about 30 officers swooped on a property in Hilltown Court just after 8.30am on Tuesday.

The raids were carried out 24 hours after 10 people were apprehended during drug raids in Douglas, Whitfield, Hilltown, Dens Road and Maryfield as part of Operation Fundamental on Monday.

About 120 officers took part in the operation following two months of intelligence gathering.

Over two days police have made 19 arrests, executed 27 warrants, recovered quantities of controlled drugs including heroin, cocaine and Diazepam and seized £20,000 in cash.

One witness saw police officers guarding the entrance to Hilltown Court while others stormed into the building.

A door was broken down during the raid.

Officers were later seen to escort two people from the building.

An eyewitness said: “There must have been at least a dozen police cars and vans.

“As I watched I saw numerous officers storm into the multi and heard a lot of shouting and banging.”

Operation Fundamental involves police working with other agencies to bring about long-term change.

The operation has been described as “unique” as information has been shared with partner agencies from the outset to enable support to be offered to vulnerable individuals who may become known during the course of the operation.

Chief Superintendent Andrew Todd, Divisional Commander for Tayside said: “We have continued with enforcement action to target those involved in drug dealing as there will be no let up in the fight against drugs in Dundee.

“A number of addresses have been targeted again today in the city to disrupt the supply of drugs into our communities.

“Dealing with those who are involved in drug dealing and abuse is not just about police enforcement, we work closely with other organisations including health, social work and housing partners, who provide support services to those individuals who require it.

“We also rely on the information we receive from the public, they know who are dealing drugs in their neighbourhoods and they need to continue to tell us who these individuals are so we can act upon that information.”

He said Fundamental is not just about enforcement but a wider change to people’s attitudes towards drugs.

He added: “We’re acutely aware of the impact drugs misuse has on our communities and we’re committed to working alongside our partners to tackle it.”

In Tayside since July, 73 people have been arrested for drug-related offences, 59 drugs search warrants were executed and more than £32,000 in cash recovered.

Council leader Councillor John Alexander said: “It’s up to all partner agencies across Dundee to ensure this operation is a success and reduces crime while improving the lives of vulnerable people.”
